Abstract (en)
[origin: DE4442362C1] Method and an appts. for blowing an oxygen-bearing gas either with or without solid matter onto a melt in a melt in a metallurgical vessel. The standard multi-function lance of relatively simple construction allows different process steps to be carried out by appropriately varying the introduction rates of individual media into the lance. In partic., the gas stream is brought into oscillations by means of an impact ring (13) forming part of the internal lance structure. The stream of gas or gas and solid matter leaves the Laval type lance nozzle (17) at a supersonic velocity.
